Subject: [PATCH net 3/9] can: dev: fix missing CAN XL support in can_put_echo_skb()

From: Oliver Hartkopp <socketcan@...tkopp.net>

can_put_echo_skb() checks for the enabled IFF_ECHO flag and the
correct ETH_P type of the given skbuff. When implementing the CAN XL
support the new check for ETH_P_CANXL has been forgotten.
